Assemble Triangle-Squares and Side Units

1. Mark a diagonal line on wrong side of each tan print and cream print 2-3/8" square.

2. Layer a marked tan print 2-3/8" square atop each blue print 2-3/8" square. Sew each pair together with two seams, stitching 1/4" on either side of drawn line (Diagram 1).

3. Cut each pair apart on drawn line to make two triangle units. Press each triangle unit open, pressing seam toward blue print, to make 280 blue triangle-squares total. Each triangle-square should be 2" square including seam allowances.

5. Sew a blue triangle-square to each end of a tan print 2x3-1/2" rectangle to make a side unit (Diagram 2). Press seams toward rectangle. The side unit should be 2x6-1/2" including seam allowances. Repeat to make 140 side units total.

2. Sew together a Square-in-a-Square unit, four side units, and four red triangle-squares in three rows (Diagram 4). Press seams toward side units. Join rows to make a Square-in-a-Square block. Press seams in one direction. The block should be 9-1/2" square including seam allowances. Repeat to make 18 Square-in-a-Square blocks total.

Assemble Nine-Patch Blocks

1. Referring to Diagram 5, sew together two red print 2x42" strips and a cream print 3-1/2x42" strip to make strip set A. Press seams toward red strips. Repeat to make a second strip set A. Cut A strip sets into a total of thirty-four 2"-wide A segments.

2. Aligning long edges, sew together two cream print 2x42" strips and a purple print 3-1/2x42" strip to make strip set B (Diagram 6). Press seams toward purple strip. Repeat to make a second strip set B. Cut B strip sets into seventeen 3-1/2"-wide B segments.

3. Join two A segments and a B segment to make a Nine-Patch unit (Diagram 7). Press seams toward A segments. The unit should be 6-1/2" square including seam allowances. Repeat to make 17 Nine-Patch units total.

4. Sew together four red triangle-squares, four side units, and a Nine-Patch unit in three rows (Diagram 8). Press seams toward side units. Join rows to make a Nine-Patch block. Press seams in one direction. The block should be 9-1/2" square including seam allowances. Repeat to make 17 Nine-Patch blocks total.

4. Aligning long edges, sew together a long inner border strip, long middle border strip, and long outer border strip to make a long border unit. Press seams toward black print strips. Repeat to make a second long border unit.

5. Using short border strips, repeat Step 4 to make two short border units.
